What Will Happen if Yellowstone Supervolcano Erupts?

How would the US be affected if the supervolcano at Yellowstone National Park erupted? That's the question scientists have been considering in the journal Geochemistry, Geophysics, Geosystems.

Experts from the US Geological Survey said while the chance of an eruption remains "very low", it has developed a computer model to simulate the distribution of volcanic ash following a "hypothetical large explosive eruption at Yellowstone".
